Original change's description:
> Add stub gpu workaround generators
>
> Like https://chromium-review.googlesource.com/c/chromium/src/+/1005362,
> this patch adds a way for Chrome and Skia to share a set of driver
> workaround names so that they can be turned on by Chrome (or Skia) as
> needed.
>
> To avoid weird cross-repository dependencies, the generator script is
> duplicated in Skia.
>
> This patch just adds a few dummy workaround names to make sure the build
> process is working. The followup to this is to add workaround init
> to GrContext/GrContextOptions and to start implementing individual
> workarounds.
>
> Implementing these workarounds is to support Chrome's "out of process
> raster" which will use Ganesh without a command buffer, and so will not
> have the workarounds that the command buffer provides.
>
> Bug: chromium:829614
